Techniques

DuroFlow: The Powerhouse of Environmental and Water Treatment, Driven by Gardner Denver Blower Division

Chapter 1: Techniques

This chapter focuses on the specific techniques enabled by DuroFlow blowers in various environmental and water treatment processes.

• Aeration: DuroFlow blowers are crucial for aeration in wastewater treatment. This process introduces oxygen into the wastewater, stimulating the growth of beneficial bacteria that break down organic pollutants. The blowers provide the necessary air flow to maintain the desired dissolved oxygen levels for optimal biological activity.
• Sludge Dewatering: DuroFlow blowers play a vital role in sludge dewatering processes, such as belt filter presses and centrifuge systems. They provide a continuous supply of compressed air to drive the dewatering mechanisms, separating water from the sludge and reducing its volume for easier disposal.
• Air Scrubbing: DuroFlow blowers are employed in air pollution control systems where they deliver air for scrubbing processes. This involves removing pollutants and odors from industrial emissions or contaminated air streams using various methods, such as wet scrubbers or dry scrubbers. The blowers ensure the efficient transport of the scrubbing medium and the removal of pollutants.
• Water Treatment: DuroFlow blowers are used in water treatment to aerate drinking water. This process removes dissolved gases like hydrogen sulfide and iron, improving the taste and odor of the water. They also provide air for other treatment processes, such as oxidation and filtration.
• Industrial Processes: Beyond environmental and water treatment, DuroFlow blowers find applications in various industrial processes. They can be used to power air-driven tools, provide air for material handling systems, and support pneumatic conveying systems.

Chapter 2: Models

This chapter explores the diverse range of DuroFlow blower models offered by Gardner Denver, catering to different application needs.

• Rotary Lobe Blowers: These blowers feature rotating lobes that trap and displace air, offering high flow rates and pressures for applications like aeration, sludge dewatering, and air scrubbing. They come in various sizes and configurations to suit specific requirements.
• Centrifugal Blowers: DuroFlow centrifugal blowers are known for their high efficiency and low noise levels. They use a rotating impeller to accelerate air and create a pressure differential for processes like air scrubbing, ventilation, and pneumatic conveying.
• Positive Displacement Blowers: DuroFlow positive displacement blowers are designed for high-pressure applications, such as compressed air systems for industrial processes. They provide constant air flow and can achieve pressures exceeding those of other blower types.
• Variable Speed Drive Blowers: Gardner Denver offers DuroFlow blowers equipped with variable speed drives, allowing for precise control of airflow and pressure. This feature helps optimize energy consumption and provides flexibility for varying process demands.

Chapter 3: Software

This chapter discusses the software solutions that Gardner Denver offers to enhance the operation and management of DuroFlow blowers.

• DuroFlow Monitoring Software: This software provides real-time monitoring of blower performance, including parameters like pressure, flow rate, power consumption, and operating temperatures. It enables early detection of potential issues and facilitates proactive maintenance.
• Remote Access and Control: Gardner Denver's software allows for remote access and control of DuroFlow blowers, enabling operators to monitor and adjust blower settings from any location with an internet connection. This feature enhances operational efficiency and reduces downtime.
• Data Logging and Analysis: The software captures and logs critical operational data, allowing for analysis of performance trends and identification of areas for improvement. This information aids in optimizing blower performance and extending its lifespan.

Chapter 4: Best Practices

This chapter outlines key best practices for installing, operating, and maintaining DuroFlow blowers to maximize their lifespan and efficiency.

• Installation Considerations: Proper installation is crucial for optimal blower performance. This includes ensuring adequate ventilation, stable foundations, and correct piping connections.
